Cautions and warnings

Current-compensated ring core double chokes

sheets.

– Particular attention should be paid to the derating curves given there. Derating must be applied

in case the ambient temperature in the application exceeds the rated temperature of the

component.

– Ensure the operation temperature (which is the sum of the ambient temperature and the

temperature rise caused by losses / self-heating) of the component in the application does not

exceed the maximum value specified in the climatic category.

– The soldering conditions should also be observed. Temperatures quoted in relation to wave

soldering refer to the pin, not the housing.

varnish agent that is used has a negative effect on the wire insulation, any plastics that are used,

or on glued joints. In particular, it is possible for washing varnish agent residues to have a

negative effect in the long-term on wire insulation.

Washing processes may damage the product due to the possible static or cyclic mechanical

loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts,

which might lead to reduced reliability or lifetime.

– Many potting materials shrink as they harden. They therefore exert a pressure on the plastic

housing or core. This pressure can have a deleterious effect on electrical properties, and in

extreme cases can damage the core or plastic housing mechanically.

– It is necessary to check whether the potting material used attacks or destroys the wire

insulation, plastics or glue.

– The effect of the potting material can change the high-frequency behaviour of the components.
